Beauty of Joseon
TikTok Influencer Content Creation Campaign

House of Marketers engineered Beauty of Joseon’s rise to category dominance, transforming the brand into the #1 Best-Selling sunscreen across Amazon and Sephora through a top-tier, authority-led K-beauty influencer strategy in the US and UK.

OUR CLIENT

Beauty of Joseon

Beauty of Joseon (BOJ) is a K-beauty skincare brand rooted in traditional Joseon Dynasty philosophy, reimagined through modern, science-led formulations and education-first routines.

OUR CLIENT

Beauty of Joseon

Beauty of Joseon blends historic Korean skincare wisdom with modern dermatological science. Known for minimalist routines, ingredient transparency, and clinical credibility, the brand has become one of the most influential K-beauty names in Western markets.

With the explosive rise of its Relief Sun: Rice + Probiotics, BOJ needed to do more than go viral – They needed to turn momentum into market dominance! And we helped them achieve this.

The Problem

Beauty of Joseon wanted to scale rapidly across the US and UK. Here, the brand faced the challenge of converting viral product momentum into sustained category leadership within the highly competitive sunscreen market.

While early traction demonstrated strong product-market fit, long-term success required a strategy that could:

  • Establish credible authority in Western markets dominated by legacy SPF brands
  • Maintain consistent demand beyond short-term viral spikes
  • Translate education-led positioning into repeatable commercial performance

To succeed, Beauty of Joseon needed a creator strategy capable of supporting long-term growth, retail expansion, and brand trust, not just awareness.

Target audience

The campaign targeted Gen Z and Millennial skincare consumers in the US and UK who actively use TikTok as a primary research and discovery platform for beauty products.

The campaign focus was on reaching:

This audience required content that balanced education, authority, and trust, rather than short-term promotional messaging, to support sustained purchase behaviour and long-term brand growth.

Our Approach

House of Marketers conducted a top-tier (Creators with 1M+ followers), authority-led influencer content creation campaign built on monthly, high-impact collaborations with a strategically-selected group of leading beauty creators and celebrity dermatologists across the US and UK.

The strategy was designed to translate Beauty of Joseon’s traditional Joseon Dynasty philosophy into a modern, education-led TikTok narrative, with Relief Sun: Rice + Probiotics positioned as the core hero product driving sustained awareness, trust, and category leadership. 

Rather than relying on high-volume creator output, the approach prioritised:

  • Long-term partnerships with top-tier creators to ensure consistency and exclusivity
  • Monthly campaign moments to maintain sustained visibility and recall 
  • Education-first content focused on ingredients, formulation, and routine integration
  • Paid amplification of high-performing assets to maximise reach and memorability

Results

Through a structured, authority-driven influencer strategy, House of Marketers delivered measurable commercial and brand impact for Beauty of Joseon across Western markets.

INFLUENCER & UGC MARKETING CASE STUDY

COSRX TikTok Shop
Influencer Marketing Campaign

COSRX TikTok Shop, Social Media Influencer Campaign

House of Marketers, global TikTok influencer marketing agency, led K-beauty creator campaign for COSRX, providing the influencer and UGC strategy generating a 2x sales increase and a 15% TikTok Shop uplift across the US, UK, and Europe through an always-on, multi-tier creator framework.

OUR CLIENT

About COSRX

COSRX is a globally recognised K-beauty brand known for ingredient-led skincare, with hero products such as Snail Mucin and a strong digital-first presence.

OUR CLIENT

About COSRX

COSRX is a globally recognised K-beauty brand known for its ingredient-led skincare philosophy and cult hero products, including Snail Mucin. With a strong digital-first foundation, the brand has built a loyal, education-driven audience across social platforms. COSRX was preparing to launch a new hair care line, requiring a creator strategy that could drive immediate sales while reinforcing long-term brand authority in highly competitive skincare markets.

The Problem

As COSRX expanded across Western markets and prepared to launch a new product line, House of Marketers was tasked with developing a creator strategy that could drive growth while preserving brand equity and long-term authority in a highly competitive beauty category.  

The brand faced three challenges:

  • Scaling TikTok Shop with conversion-first execution. TikTok Shop presented a high-growth opportunity, but scaling efficiently required a creator strategy built specifically for conversion, alongside awareness-led reach.
  • Differentiating in a saturated global skincare market. Intense competition across K-beauty and global skincare categories made standout visibility and sustained creator-led differentiation critical.
  • Launching a new product line without diluting brand equity. The introduction of a new hair care line required rapid market penetration while preserving COSRX’s existing skincare authority and brand trust.

To succeed, COSRX needed a strategy that could drive immediate sales while building durable, creator-led credibility to support long-term growth.

Target audience

COSRX’s campaign was targeted at Gen Z and Millennial beauty consumers across the US, UK, and Europe who actively discover products through TikTok routines, reviews, and creator-led education.

The focus was on reaching:

This audience required content that balanced credibility, clarity, and conversion, rather than just promotional messaging.

Our Approach

House of Marketers built an always-on, full-funnel K-beauty influencer engine designed to do one thing exceptionally well: convert at scale. House of Marketers deployed a multi-market creator framework to ensure that COSRX never dropped out of the conversation. House of Marketers’ role focused on creator-led amplification, supporting their TikTok Shop performance, and UGC execution, supporting both online and offline brand moments through influencer activity.

Our strategy was built on:

  • A multi-tier creator mix, combining top-tier routine creators, mid-tier reviewers, and micro and nano TikTok Shop converters
  • Monthly gifting waves focused on hero products and new launches to sustain momentum
  • Tailored product education, ensuring creators produced high-quality, conversion-driven content
  • Market-specific execution across the US, UK, and Europe to maintain relevance at scale.

As part of COSRX’s European expansion, the brand launched a 17-day pop-up activation in Paris, with House of Marketers supporting the activation through influencer-led amplification and creator visibility.

Located on a high-footfall street, the pop-up relied primarily on organic foot traffic to drive interest, supported by PR and influencer visibility, allowing the brand to connect directly with consumers and build early momentum in the market.

The 17-day pop-up event in Paris drove 3.2M organic views and an 18% uplift in DTC sales.

Results

During the campaign, COSRX turned into a TikTok Shop growth engine. Across COSRX’s K-beauty influencer and UGC campaign, House of Marketers delivered scalable, conversion-led performance on TikTok by combining always-on creator activity with education-first, routine-based content optimised for TikTok Shop.

The campaign was executed concurrently across multiple Western markets, demonstrating House of Marketers’ ability to scale creator-led TikTok commerce without compromising consistency or performance.
